Answer:
The correct option is;
A warm front is approaching the city and temperatures will increase
Explanation:
A low pressure forms by the movement of air away from a particular spot such that the pressure reduces. The movement of air away from a spot occurs when there is a boundary of warm and cold air such that the air moves to maintain a uniform temperature.
Low pressure centers are associated with warm fronts, resulting in the fall of barometric pressure or observed low pressure and are characterized by a rise in temperature.
Galvanometer:
its an instrument for detecting small electric currents.
Electric motor:
its an electrical machine that converts electrical energy into mechanical energy.
I believe those all look correct!
Answer:
66622.653 mi/hr
Explanation:
The average speed at which the Earth rotates around the Sun = 29.783 km/s
Also, The conversion of km to miles is shown below:
1 km = 0.621371 miles
The conversion of s to hr is shown below:
1 s = 1 / 3600 hr
So,
Thus,
<u>The average speed at which the Earth rotates around the Sun in miles per hour = 66622.653 mi/hr</u>
Non metallic elements pull electrons from metallic elements so effectively during a reaction because they have a tendency to gain electrons and tend to be small in size.
<span>Non metallic elements have higher electronegativities than metals. The atoms of nonmetals tend to gain electrons in order to acquire a noble gas electron configuration. This gives them a net negative electric charge. </span>
